Subject: This patch adds a flag in MCAsmInfo that indicates whether dwarf
 register numbers should be printed instead of symbolic register names in
 MCAsmStreamer::EmitRegisterName. This is necessary because some versions of
 GNU assembler won't accept code in which symbolic register names are used in
 cfi directives. There is no change in behavior unless the flag is explicitly
 set to true by a backend.
